As Fangy's fins are so successful, I filleted my 21cm 55deg fin. It made a big difference, took all the wishy washy feeling out of it.
So now I'm going to try it on 'ken's delta, Ken isn't overly fond of this fin, so with any luck he'll notice an improvement.
If he doesn't we'll just grind it off again.

Just in case it works well, and all you disgruntled delta owners want to try something similar, I'm documenting the process.

So I don't have the embarrassment of a fin stuck in a board, I've made a jig to hold the fin while I glass the fillet on.



Some acrylic contact cemented to scrap chip board.

I've sanded the fin where the fillet's going and removed the rubber buffer from under the front overlap.

Cut some rovings to form the bulk of the fillet, some glass to go under and over.


More tomorrow after I've laid it up.
